About the NRF24 PCB

NRF24 is an open source PCB design by sneakylizard123-4, published on GitHub under the CERN-OHL-P-2.0 license. It is a 4-layer board measuring 50 × 30 mm, with 38 components from 26 distinct parts.

Other key parts include the NRF24L01P, TLV75733PDBV and RFX2401C. By type, the board carries 22 capacitors, 5 inductors, 5 resistors, 3 ICs, 2 connectors and 1 crystal.

It belongs with the rf & radio and dev boards & breakouts designs in this gallery.

From the project

A small 2.4GHz module based on the nRF24L01P+, with an SMA jack for an external antenna, an on-board RFX2401C PA/LNA for extra range, and a breadboard friendly SPI header. Runs from 3.3V or 5V off an on-board LDO.

- nRF24L01P+ 2.4GHz transceiver - RFX2401C external PA/LNA for roughly +20dBm in TX and LNA gain in RX - Discrete LC balun + harmonic filter - LC match and DC block from the PA/LNA out to the SMA jack (0.3pF and 1.5pF C0G caps, 2.3nH to 12nH inductors) - Right-angle SMA jack mounted on the board edge, for a real whip or panel antenna - 16MHz crystal with matched load caps and bias…
